Abstract

See full text

Embodiments relate generally to systems and methods for decommissioning a pipeline. The system may comprise a mechanical assembly and chemical assembly. The mechanical assembly may include a main body and contact assembly. When the mechanical assembly is provided in the pipeline, the contact assembly is configurable to contact with the pipeline's interior wall. The chemical assembly may be arranged serially in line with the mechanical assembly. The chemical assembly may include a front section having a cross-sectional portion configurable to resemble the cross-section of the pipeline. The chemical assembly may also include a rear section having a cross-sectional portion. The front and rear sections may be arranged in such a way that, when the chemical assembly is provided in the pipeline, the cross-sectional portions of the front and rear sections cooperate with the pipeline's interior wall to form a chamber operable to receive and house a removal medium.
